Super ContributorHi @Ppavan
Are you asking on how to edit the Memory Contents in the ISMCE?
You can edit the contents of instances by typing over the existing values directly into the Hex Editor pane.
You may checkout the User Guide below Section 5. In-System Modification of Memory and Constants:

New ContributorHi Richard,
Thank you for the reply.
I want to modify a constant (if that is possible) through ISMCE.
I am currently using tcl scripts, not GUI. I have working scripts to read and write data to memory using ISMCE.
I want to do the same to read and modify a constant through ISMCE.

Pavan
Super ContributorYou can refer to the scripting available for ISMCE in the User Guide below.
I am more familiar with GUI though. You may need to try out which one works best for you.
I think the write_content_to_memory tcl command is the closest to what you descript.

New ContributorHi Richard,
I already have the working scripts to read and write data in memory.
I want to know if there is a possibility to read and modify a constant value (not in memory).
I have read somewhere that Quartus implements constants in registers rather than LUTs when need to be modified using ISMCE.
I want to know how to do this.

Pavan
New ContributorHi,
I believe that a way to define constants that can be modified using ISMCE in the earlier quartus versions was through LPM_CONSTANT IP.
In quartus 19.4/19.2 versions, I do not see this IP.
Is there an alternative to this?
